[PATCH 0/3] phy: cix: add Sky1 USB/DP combo PHY

[Gary Yang]

This series adds support for the USB/DP combo PHY found on the CIX Sky1
SoC. Each PHY instance provides one SuperSpeedPlus USB lane and one
DisplayPort lane of a USB Type-C port, with plug orientation and USB/DP
lane muxing handled through the S5 system controller.

The PHY registers a Type-C switch and mux so that the connector driver
owns orientation and mode decisions, and exposes the USB and DP lanes as
separate child PHYs so that the USB and DP controllers can bind to them
independently.

Patch 1 documents the binding, patch 2 adds the driver, and patch 3 adds
the SoC nodes and enables them on the Radxa Orion O6.

The driver has been built for arm64 with the PHY enabled both built-in
and as a module. dt_binding_check, dtbs_check and checkpatch --strict
pass.
